本文对中国境内晚新生代火山岩和第四纪地层的古地磁学研究,肯定了一些短周期极性事件的存在。在对比了世界各地的古地磁资料后,建立了2.48 Ma以来的地磁极性年代表。
In this paper, the paleomagnetic study of Late Cenozoic volcanic rocks and Quaternary strata in China confirmed the existence of some short-period polar events. After comparing the paleomagnetic data from all over the world, the geomagnetic polarity year since 2.48 Ma has been established.
